This is controlled by "swappiness" which can have a value between 0 and 100 - 0 only swap if space in RAM runs out, 100 swap a lot
Ubuntu has 60 as default and so does Mint while Arch probably has a lower value
To find your swappiness
Code: Select all
cat /proc/sys/vm/swappiness
Code: Select all
gksu gedit /etc/sysctl.conf
After the next reboot the new swappiness is used and you should not see any use of the swap partition
